This is assuming the noise is in the front.
Is the noise worse when turning one way more than the other? This could still be a wheel bearing if it is.
From a stop turn the steering wheel all the way to the left and the move the truck slowly in a circle. Do this also to the right. Is there a noise then? Is it in the front end?
If yes, it is most likely a CV joint. Look to see if any of the boots are ripped. CV joints usually create more of a clunking noise.
Another idea. Are all of the lights for the 4x4 and the front axle out? I had a lot of front end noise in mine because the front axle wasn't disengaging when I shifted out of 4WD. This ended up being the vacuum switch on the transfer case.
To check if it may be the u-joints or carrier bearing on the driveshaft, jack up the rear and support it with jack stands. Check for play in the u-joints by grasping the drive shaft and moving up and down at each u-joint. Put the truck in neutral and turn the driveshaft 1/4 turn and check each u-joint again. With the truck well supported and in 2WD, start the truck and run it in gear up to 35-40 MPH. Is the noise reproduced now? If so, it is the u-joints and/or carrier bearing.
